5% Lugol's Solution Iodine Drops 4oz — Classic Daily Formula, 4oz bottle, ~60-day supply

5% Lugol's Solution is the original 1829 formula: molecular iodine (I₂) and potassium iodide (KI) in purified water, with nothing else added — 2.5x the iodine per drop vs. our 2% formula. Every bottle is manufactured in the U.S.A. by Lugols Originals using high-purity ingredients.

Why Lugol's Solution?
